This statement makes no sense. If you use the old legacy uImage format (which is deprecated, and should be replaced by FIT images), you specify the entry point address to the kernel, and the load address (i. e. where in RAM the image should be placed). These two parameters to themkimage commansd are registered in the image, and they are in no way related to any U-Boot environment variables, nor can any environment variable settings influence these.
Of course you should make sure that memory area where you dowenload the image does not overlap the area where it gets unpacked / copied to, but the same issues exist with zImage files.
Please fix the commit message to describe correctly what you want to acchieve.
Best regards,
